如何在Xcode 6中重置导航控制器？

Question

Im working on an App for iOS, thats uses the navigationController to switch betweens views. I'm trying to return from to the root viewcontroller from the third view.
I have succeeded in the Main.Storyboard, with dragging a button from third to root view, but then the NavigationController just continues the stack.

Is it possible to make a command from third view, to return to root ViewController, without the NavigationController Bar showing the "Back" button and keeping track and without reseting any Bools.

Answer 1

您可以使用[UINavigationCobtroller popToRootViewControllerAnimated:]将所有视图层次结构关闭到第一个，但对于其余问题，您可以在SO上找到很多答案。

Answer 2

If you want to hide the back button from the navigation bar.Then write the code in third view's viewDidLoad or in viewWillAppear-

self.navigationItem.hidesBackButton=YES;

And Now write the code in the body of the action button.Such as-

[self.navigationController popToRootViewControllerAnimated:YES];

Let me know if it works for you.Thank you
